The Introversion Store lists a status next to each of your orders; right now, my special edition order is listed as 'Order Confirmed', while my previous orders all have 'Shipped', and I presume that is the case for skull13 also.
skull13, if you know it hasn't been shipped, there's no reason for concern, only patience -- your order is certainly recognised by Introversion if it's in the store (unless it's says 'Payment Pending' or something similar, in which case there probably is an issue). There's only really need for concern if it's been over a month after shipping -- for an international order, that is: I don't know where you are -- and there's still no sight of it. There are shipping time estimates on the IV store
